Does Using a Repaired Tire Have Any Impact?
2 Answers
The impact of using a repaired tire depends on the extent of the damage. If the tire was simply punctured by a nail, it can last as long as the other tires after being repaired. As long as the repaired tire doesn't leak air, its quality remains the same with no adverse effects. However, if the puncture is large, such as from a knife cut, there can be significant safety risks. If the damage occurs on the tire's sidewall, it must be replaced immediately. For tread punctures caused by nails or other objects, repairs are possible if the hole diameter is less than 6mm; otherwise, the tire must be replaced. Additionally, if the tread is peeling or the tire body is severely damaged, a new tire is necessary.
The impact of using a repaired tire varies from person to person, but from a safety perspective, there are indeed potential risks. The location of the repair is most critical—holes in the central tread area can be fixed with plugs or mushroom patches, but sidewall damage requires a new tire to avoid blowout risks at high speeds. Repaired tires are prone to slow air leaks, so weekly pressure checks are essential to maintain proper inflation. High-speed driving increases temperature, weakening the repaired area and affecting stability. Personally, I recommend avoiding long-distance high-speed trips after a repair, especially if the tire is severely worn or over five to six years old. Regular balance tests at the repair shop and keeping an air pump in the car for emergencies are wise. Safety always comes first, especially with family onboard—don’t compromise over small savings; replace tires decisively when needed.
